Background Emergency department (ED) visits are common for older patients with chronic, life-limiting illnesses and may offer a valuable opportunity for clinicians to initiate proactive goals of care conversations (GoCC) to ensure end-of-life care that aligns with the patients' values, goals, and preferences. Objectives The purpose of this study is to assess whether GoCC are occurring with patients in Department of Veteran Affairs (VA) EDs, to characterize these patients' goals of care and life-sustaining treatment (LST) decisions, and to examine the extent to which palliative or hospice consultations occur following the ED visit. Design We conducted a cross-sectional retrospective study using health record data. Settings/Subjects A total of 10,780 patients receiving care in VA, whose first GoCC occurred during an ED visit. Results Of the patients in the study, approximately half were at least 70 years of age, three-quarters were white, and half had multiple serious disease comorbidities. The percentage of patients who desired cardiopulmonary resuscitation was lower among the highest risk (i.e., of hospitalization and death) patients (64% vs. 51%). The percentage of patients wanting other LSTs (e.g., mechanical ventilation) was higher among the lowest risk patients; and the percentage of patients requesting limits to LSTs was highest among higher risk patients. Eighteen percent of patients had a palliative or hospice care consult within three months of their ED visit. Conclusions In this study, we verified that GoCC are being initiated in the ED with Veterans at differing stages in their illness trajectory and that higher proportions of higher risk patients preferred to limit LSTs.Background A combination of clinical and electrocardiographic risk factors is used for risk stratification in Brugada syndrome. In this study, we tested the hypothesis that the incorporation of latent variables between variables using nonnegative matrix factorization can improve risk stratification compared with logistic regression. Methods and Results This was a retrospective cohort study of patients presented with Brugada electrocardiographic patterns between 2000 and 2016 from Hong Kong, China. The primary outcome was spontaneous ventricular tachycardia/ventricular fibrillation. The external validation cohort included patients from 3 countries. A total of 149 patients with Brugada syndrome (84% males, median age of presentation 50 [38-61] years) were included. Compared with the nonarrhythmic group (n=117, 79%), the spontaneous ventricular tachycardia/ ventricular fibrillation group (n=32, 21%) were more likely to suffer from syncope (69% versus 37%, P=0.001) and atrial fibrillation (16% versus 4%, P=0.023) extracting latent features between different variables.Studies using cotinine levels to define smokers have generally failed to detect an association between smoking and multiple sclerosis (MS). Using a Swedish population-based case-control study, we show that associations in relation to MS risk and progression differ considerably depending on how smoking is measured. The risk of conversion into secondary progressive disease was increased among smokers when self-reported smoking history, but not presumed cotinine levels, was used to define smokers. Defining smoking by cotinine levels without distinguishing between different sources of nicotine may lead to severely biased estimates of the association between smoking and both MS risk and progression.
  To investigate the performance of a narrow-scope knowledge-based RapidPlan (RP) model, for optimisation of intensity-modulated proton therapy (IMPT) plans applied to patients with locally advanced carcinoma in the gastroesophageal junction.
 
  A cohort of 60 patients was retrospectively selected; 45 were used to 'train' a dose-volume histogram predictive model; the remaining 15 provided independent validation. The performance of the RP model was benchmarked against manual optimisation. Quantitative assessment was based on several dose-volume metrics.
 
  Manual and RP-optimised IMPT plans resulted dosimetrically similar, and the planning dose-volume objectives were met for all structures. Concerning the validation set, the comparison of the manual vs RP-based plans, respectively, showed for the target (PTV) the homogeneity index was 6.3 ± 2.2 vs 5.9 ± 1.2, and V98% was 89.3 ± 2.9 vs 91.4 ± 2.2% (this was 97.2 ± 1.9 vs 98.8 ± 1.1 for the CTV). Regarding the organs at risk, no significant differences were report-based optimisation could be displayed. The data also showed a high correlation between predicted and achieved doses in support of the valuable predictive power of the RP method.Background The impact of the new 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guideline on dementia risk at the population level has not been evaluated. Methods and Results We studied dementia-free participants in the ARIC (Atherosclerosis Risk in Communities) Study cohort in 1987 to 1989. Hypertension was defined by 2003 Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure and 2017 ACC/AHA guidelines using blood pressure measured at baseline. Dementia was defined using adjudicated consensus diagnoses, informant telephone interviews, and discharge codes from hospitalizations and death certificates. Cox regression estimated hazard ratios (HRs) for dementia and 95% CIs by hypertension categories, adjusting for confounders.  https://www.selleckchem.com/products/Clopidogrel-bisulfate.html  Population attributable fraction of dementia was calculated by hypertension categories. Among 13 971 participants followed up for a median of 23 years, 1381 dementia cases were identict on dementia incidence using ACC/AHA categories was similar to the impact of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.Malnutrition is associated with treatment-related toxicities (TRT) in adults with solid tumors and in children with leukemia. Few studies have assessed whether malnutrition in pediatric patients treated for solid tumors impacts risk for TRT, relapse, and/or survival. To address this knowledge gap, this retrospective study evaluated the association between body mass index (BMI) at diagnosis, and imputed BMI during therapy, on the prevalence of TRT, specific toxicities, relapse, and survival in pediatric patients with solid tumors treated with cisplatin-containing regimens. Kaplan-Meier curves and regression models evaluated the association between patient-specific characteristics (including BMI) and TRT, relapse, and survival. The cohort included 221 patients, of whom 22% were malnourished at diagnosis (10% were underweight and 12% were obese). Most patients (60%) experienced at least one severe TRT, and 30% developed more than one severe TRT. Most patients with obesity at diagnosis remained obese during therapy (62%).
